#1
Daneng Li, Enrique Soto-Perez-de-Celis, Arti Hurria
Cancer is a disease of older adults, and the majority of new cancer cases and deaths occur in people 65 years or older. However, fewer data are available regarding the risks and benefits of cancer treatment in older adults, and commonly used assessments in oncology fail to adequately evaluate factors that affect treatment efficacy and outcomes in the older patients. The geriatric assessment is a multidisciplinary evaluation that provides detailed information about a patient's functional status, comorbidities, psychological state, social support, nutritional status, and cognitive function...

Sideroblastic anemias are a rare group of disorders resulting from defective iron incorporation during heme synthesis and hence characterized by anemia and presence of ringed sideroblasts in bone marrow. The most common form is an X-linked disorder caused by mutations in ALAS2 gene. In the current paper, a case of X-linked sideroblastic anemia caused by a novel homozygous deletional mutation in exon 10 of ALAS2 gene is presented. The female infant developed moderately severe anemia at 6 months of age, which did not improve despite adequate nutritional support...

Fabricio Rocha Vieira, John Andrew Pecchia
Substrate preparation (i.e., composting) for Agaricus bisporus cultivation is the most critical point of mushroom production. Among many factors involved in the composting process, the microbial ecology of the system is the underlying drive of composting and can be influenced by composting management techniques. Pasteurization temperature at the beginning of phase II, in theory, may influence the bacterial community and subsequently the "selectivity" and nutrition of the final substrate. Therefore, this hypothesis was tested by simulation in bioreactors under different pasteurization conditions (57 °C/6 h, 60 °C/2 h, and 68 °C/2 h), simulating conditions adopted by many producers...

The striatum is anatomically and behaviorally implicated in behaviors that promote efficient foraging. To investigate this function, we studied instrumental choice behavior in mice lacking GPR88, a striatum-enriched orphan G-protein-coupled receptor that modulates striatal medium spiny neuron (MSN) excitability. Our results reveal that hungry mice lacking GPR88 (KO mice) were slow to acquire food-reinforced lever-press, but could lever press similar to controls on a progressive-ratio schedule. Both WT and KO mice discriminated between reward and no-reward levers; however, KO mice failed to discriminate based on relative quantity- reward (1 versus 3 food pellets) or effort (3 versus 9 lever presses)...

OBJECTIVES: According to a report by the United States National Health and Nutrition Examination Survey, nearly 60% of patients with diabetes have more than one complication caused by chronic diabetes. Type 2 diabetes is a multifactorial metabolic disorder that accounts for more than 95% of people with diabetes and usually requires multitargeted therapeutic interventions. It arises due to insufficient insulin secretion or its action or both. Recently, we reported that the oral administration of gymnemic acid, trigonelline and ferulic acid in the ratio of 2:3:1 (GTF-231), a mixture of 3 phytoingredients at a concentration of 300 mg/kg body weight significantly improved the glucose homeostasis in rats with low-dose streptozotocin-induced type 2 diabetes that were fed with high-fat diet...

BACKGROUND: Mild or pre-frailty is common and associated with increased risks of hospitalisation, functional decline, moves to long-term care, and death. Little is known about the effectiveness of health promotion in reducing these risks. This systematic review aimed to synthesise randomised controlled trials (RCTs) evaluating home and community-based health promotion interventions for older people with mild/pre-frailty. METHODS: We searched 20 bibliographic databases and 3 trials registers (January 1990 - May 2016) using mild/pre-frailty and associated terms...

BACKGROUND: Despite the reduction in glycemic derangement in patients with type 1 diabetes mellitus (T1D) through dietary and therapeutic adjustments implemented before, during and after continuous exercise, evidence for its effectiveness with intermittent forms of exercise, such as soccer, is still lacking. METHODS/DESIGN: We designed a study protocol for a randomized, crossover, double-blinded, controlled trial, for the evaluation of the effect that a strategy of dietary and therapeutic modifications may have on safety and performance of persons with T1D in soccer training sessions and cognitive testing...

OBJECTIVE: Breastfeeding during infancy is associated with a lower risk of attention-deficit/hyperactivity disorder (ADHD). Although this is presumably due to breast milk's nutritional advantages, formula-fed infants have, until recently, also been exposed to bisphenol A (BPA), a neurotoxic chemical previously used to manufacture baby bottles and formula cans. Our goal was to examine the association between formula feeding and preschool ADHD in 2 comparable, serial cohorts of preschool children who differ in BPA exposure during infancy...

Enteral nutrition is preferred over parenteral nutrition as a result of the greater safety of enteral nutrition therapy and comparative convenience. A wide variety of enteral nutrition products have been developed, including disease-specific products to help manage the nutritional needs of patients with kidney failure, liver failure, lung disease, diabetes, and other conditions. An assessment of each patient's nutritional needs and digestive function should be conducted prior to initiation of enteral nutrition therapy...

Poor maternal nutrition during gestation has been linked to poor growth and development, metabolic dysfunction, impaired health, and reduced productivity of offspring in many species. Poor maternal nutrition can be defined as an excess or restriction of overall nutrients or specific macro- or micronutrients in the diet of the mother during gestation. Interestingly, there are several reports that both restricted- and over-feeding during gestation negatively affect offspring postnatal growth with reduced muscle and bone deposition, increased adipose accumulation, and metabolic dysregulation through reduced leptin and insulin sensitivity...

Toxoplasma gondii is considered as one of the most successful intracellular pathogens, because it can reproduce in varied nutritional milieus, encountered in diverse host-cell types of essentially any warm-blooded organism. Our earlier work has demonstrated that the acute (tachyzoite) stage of T. gondii depends on cooperativity of glucose and glutamine catabolism to meet biosynthetic demands. Either of these two nutrients can sustain the parasite survival; however, what determines the metabolic plasticity has not been resolved yet...

REVIEW
Paul J Price
Cell culture medium is a complex mixture of nutrients and growth factors that, along with the physical environment, can either help or destroy your experiment or production run. Nutritional requirements differ with different cell types and functions, as do optimal pH and osmolality. As cell growth proceeds, different cells will utilize amino acids and other components at different rates. By controlling for ammonia, free radicals, heavy metal toxicity, pH shifts, fluctuations in osmolality, nutrient depletion, and chemical and biological contaminants, you will optimize the chances of success...

Octopus vulgaris aquaculture is limited due to poor biological knowledge of the paralarval stages (e.g., digestive system functionality), their nutritional requirements (e.g., adequate live diet) and standardization of rearing techniques. These factors are important in explaining the high mortality rate observed in this developmental stage under culture conditions. For a better understanding of nutrition biology of this species, we investigated the 3D microanatomy of the digestive tract of the embryo and paralarvae during the first month of life...

Organisms must execute metabolic defenses to survive nutrient deprivation. We performed a genome-wide RNAi screen in Caenorhabditis elegans to identify fat regulatory genes indispensable for starvation resistance. Here, we show that opposing proteostasis pathways are principal determinants of starvation survival. Reduced function of cytoplasmic aminoacyl tRNA synthetases (ARS genes) increases fat mass and extends starvation survival, whereas reduced proteasomal function reduces fat and starvation survival. These opposing pathways converge on AMP-activated protein kinase (AMPK) as the critical effector of starvation defenses...
